| 摘 要： | 天荒坪电站上水库采用全库盆沥青混凝土防渗,仅进出水口位置未设置.为防止库水下渗到沥青混凝土库盆的下卧层,设置了截水墙和防渗帷幕,该帷幕长期处于动水压力下,性能削弱较严重,需要补强.为了保证帷幕补强的耐久性,进行了试验,对灌浆的参数和材料进行比选,并用于最终补强施工.

| Abstract: | Except the inlet/outlet location,anti-seepage asphalt concrete was used for the whole upper basin of Tianhuangping power station.To prevent leakage from the reservoir to the underlayer of basin,cut-off wall and curtain grouting were set.Because of the long-time effect by hydrodynamic pressure,the curtain had been weakened and reinforcing was necessary.Grouting test was made to ensure the durability of reinforcing work.The optimal grouting parameter and material were selected and used for construction. |
